Specification of Letters Patent.

Patented March 17', 1908.

Serial No. 154,187.

To all whom 'it may concern:

Be it known that I, FREDERICK PURDY, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Automatic Time- Stamps, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in which corresponding letters of reference in the different iigures indicate like parts.

My invention relates particularly to time stamp devices in which thecharacter of the impression adapted to be made is automatically varied.

It is the object of the present invention to provide a self inking time stamp adapted to print time in which proper contact of the impression device or mechanism with the surface being stamped will be insured without the use of a platen, so that the size of the article which may be stamped thereby is unlimited.

One of the objects of the present invention is to connect the horologic motor with the impression mechanism in a portable time stamp device, in such a manner that said motor may remain in a stationary position while said impression mechanism is moved into engagement with the surface to be stamped to make an impression.

Another object of the invention is to provide means for detachably connecting the motor with the impression mechanism, so that said impression mechanism may be disconnected from the motor when it is moved to make an impression, and which will syn chronize said impression mechanism with said motor after each impression has been made.

A further object is to so combine the time train with the stamping mechanism and with the clock-dial and hands, that the device may not only be utilized as a clock for ordinary time keeping purposes, but that errors may be avoided in stamping by 'first determining by a glance at the clock-dial, whether or not the time indicated is correct-thus insuring the accuracy of the registration before the impression is made.

I accomplish said objects through the instrumentalities hereinafter more particularly described and deiinitely pointed out in the claims.

In the drawings, Figure 1 is a central, longitudinal vertical sectional view of a reversible hand-stamp embodying the features of my invention, Fig. 2 is a transverse vertical sectional view thereof; Fig. 3 is a face view of the stamping dies; Fig. 4 is a like view of the inking-pads arranged to co-act therewith, Fig. 5 is a central vertical sectional view in detail through one of said inking-pads and dies as they are shown in normal contact; Fig. 6 is a front face view of a stamp showing a modiiication of said invention; Fig. 7 is a side view thereof partly in vertical section, and, Fig. 8 is a plan view of a portion of said device in which a part of the case is broken away to show the clock train.

Referring to the drawings, 1 represents the main frame of a hand stamp preferably of the reversible type, which frame is provided with. a casing plate 6 and is also provided with gage parts 1a to bear upon the surface to be stamped and thereby support said frame in a stationary position when an impression is being made. Attached to or forming a part of the upper portion of said frame is a casing 2 within which is inclosed a clock train having vertical arbors, the main arbor 3 of which is driven by the usual coiled spring inclosed within a drum 4. A secondary arbor 5, is connected by means of gears with the arbor 3, and projects through the lower plate 6,-a disk or circular plate 7, shown in detail in Fig. 5, being attached to the lower end thereof, so as to rotate therewith. Said disk is adapted to rotate once per hour and is provided with a V-shaped projection 8 upon its lower face, for the purpose hereinafter stated, which projection is preferably in the plane of. its axis. The disk 7 is cut away as shown in Fig. 5, leaving an annular peripheral space which is filled in by means of a ring 9 of absorbent material, to form an ink-pad. Like members, or elements 10 and 11, having like projections 12 and 13 respectively, Fig. 4, and like ink-pads 14, 15, are mounted respectively upon the lower ends of the arbors 16 and 17, Fig. 1, the former of which makes one complete revolution in twelve hours, while the latter rotates once in twenty-four'hours. Adjacent to the pads 9, 14 and 15 is a stationary pad 16, Figs. 1 and 4, of corresponding thickness.

Beneath the casing 2 which holds the clock train, is a reversible plate 17a, having cams 18, 18 depending from its ends. Said cams are connected by means of wrist-pins 19, 19, Fig. 1, with a movable U-shaped bail 20,

raised position.

e plate 17 is in its normal position.

havi'ng a tubular handle 21 at the top, whichv handle is adapted to telescope with a tube 22, having a spiral spring 23, Fig. 1, for holding the reversible plate in its normal Vertical slots 24 serve to guide the pins 19 while studs 25 and 26 serve, When the handle is depressed, to engage the cams 1S, so as to cause the plate 17ato be completely reversed,l thereby enabling it to be impressed upon the printing surface.

The revolving part carrying the printing surface which may be termed the tumbler completes its revolution in making an impression a short time before the printing sur face engages the surface to be impressed, so

' that the impression mechanism artakes of a right line movement in approac iing the surface to be impressed; in this manner a clear and clean cut impression results and the 20 blurring oi the impression is prevented.

Impression or printing diesi7, 28 and 29, are pivotally mounted upon the reversing Y plate 17a, said dies being in the Jform oi disks as shown, and provided with pivot stems 30,

to retain them in place While leaving them free to rotate. The position of said several dies conforms respectively with those of the disks 7, 10 and 11, and said dies are provided with slots or indentations 31, 32 and 33 to 3o receive the projections 8, 12 and 13 respectively upon the disks 7, l() and 11, in the manner clearly shown in Fig. 5, when the The projections described upon the revoluble disks 35 which are driven by the time train, are not only intended to engage with the printing disks to cause then' rotation, but are designed to act as synchronizing elements as Well. That is to say, when the printing dies 40 are lowered to make the impression, they cease to rotate, While the parts by which they are driven go on. This stoppage of the dies e during the interval required to make an ordilnary impression, Would be so slight as to be inappreciable; but should the time be eX- cessive, the beveled projections upon the disks would, upon entering the depressions of the printing dies, cause them to at once rotate suiiiciently to synchronize With the separate elements oi the time train by which they are driven.

The printing dies 27 and 28, are marked with the minutes and hours respectively, in raised numbers, While the characters A. M.

and I). M. are formed upon the die 29. Charas the generic claims herein are concerned.

In operating my improved device it will be seen that the dies and hiking-pads are in normal contact, while the time train remains stationary and is not disturbed by the oi the reversal nor by the impact oi the impression.

In the device which I have described, the necessity of providing the stamp with a platen is obviated, as the gage parts insure properly setting the device in position for making an accurate impression, and therefore, the device is not limited as to the size of the article it may stamp. This stamp may be readily moved from place to place for use, and as it is automatically inked, the impressions may be produced in rapid succession. The danger of the horologic motor becoming deranged by the jar when the stamp is oper ated, is lessened in the present construction by mounting the motor upon the frame to remain in a stationary position. There are of course, other Ways than those shown, in which the horologic motor may be connected With the impression mechanism so that the latter may be moved relative to the former and yet be operated thereby, and this invention, therefore, contemplates coupling the impression mechanism with the motor in any desired manner.

In my invention it is not essential that the printing dies be driven by the parts carrying the movable inking pads and the printing dies may be driven in any desired manner. Moreover, the inking pads need not be directly connected with the motor to be positively driven but may be caused to revolve in unison with the impression means in any other desired manner.

In Figs. 6 to S inclusive, I have shown a modiiication oi said invention, which consists in placing the clock train in a separate case 34, upon the front side of the case 2, and connecting the same by means of beveled gears 35, 36 with the arbor adapted to drive the disk 7, the remaining disks being driven by suitable intermediate gears to cause them to rotate in the proper relative time. The advantage oi this construction is that it enables the user of the stamp. to determine at all times, by merely looking at the dial, Whether the stamp will give the correct time impression, or not, thereby avoiding the making of an erroneous impression.

The device herein described is adapted to make the impression by printing, but, of course, it will be understood that the impression might be made in other Ways, as for example by stamping, embossing or other- Wise.

It will be noted that the casing of the time stamp normally incloses the hoi'ologic motor and the impression means, thus protecting the same against dust, dirt and injury.

The device shown and described herein is only one of the embodiments of which my claimed herein and I reserve for said invention is susceptible, and, therefore, the various modifications which may be made in the details of construction, arrangement, and combination of parts herein set forth are intended to fall within the scope of the claims appended hereto.

In the application filed April 24, 1903, Serial No. 154,057, I have shown a modiiication of the present invention wherein the horologic motor is movable with the impression means in making an impression, the motor being thus carried upon the frame indirectly instead of being stationarily mounted thereon as illustrated in the present application. I have inserted in the present application generic claims covering the structure of the application above mentioned as well as the structure of the present invention and have claimed in said application Serial N o. 154,157 the species of the broad invention wherein the horologic motor and the impression means are mounted to move together 5 and I have inserted in the present application claims drawn to the species illustrated herein wherein the horologic motor is mounted stationarily upon the frame and the impression means is separable therefrom or relativelyT Vmovable with respecty thereto in making an impression. It will be understood that the generic claims hereinreferring to the horologic motor being mounted, supported or carried upon the frame contemplate that the motor may be stationarily mounted thereon or may be indirectlyT carried thereon by being placed upon the part of the stamp which is moved in making the impression.

I have iiled anumber of applications embodying species of the generic invention applications the several species therein disclosed., and it will be understood that said applications are subsidiar)T to thepresent application g said applications are identified as follows: Serial Nos. 158,408, 158,409, 158,410, 158,411, filed May 23rd, 1903, Serial Nos. 159,309, 159,310, filed May 29th, 1903, and Serial No. 164,410, filed.
